Patent DE-3201023-A1 (DE)
Title: Valve spring retainer for valve operating mechanisms of internal-combustion engines
Inventor: AICHELE WILFRIED DR
IPC: F01L3/10
Filed: 1982-01-15
Abstract: A valve spring retainer is proposed, which is used for valve operating mechanisms of internal-combustion engines. The valve spring retainer essentially consists of a chopped fibre reinforced thermoset synthetic resin compound. For receiving radial forces in the conical region (2), the valve spring retainer advantageously has a sleeve (3) of steel or fibre composite, if appropriate with radial ribs (4). In addition, to reduce wear, metal discs (5 and 6) may also be arranged on the spring seats. The valve spring retainer has a significantly lower mass than the previous valve spring retainers produced from steel and therefore allow higher speeds and shorter valve control times, so that the efficiency of the engine can be increased. <IMAGE>

Title: Frame advance setting mechanism of a film feed device in a still camera for circular film discs
Inventor: HACKENBERG HUBERT ING GRAD
IPC: G03B1/08
Filed: 1982-02-18
Abstract: The aim is to produce a frame advance setting mechanism of a film feed device in a photographic still camera for preferably circular film discs which are arranged in preferably flat film cassettes and have image recording surfaces provided at equal spacings, preferably equal angular spacings, each image recording surface being assigned a cutout in the film disc or in a disc connected to the latter in a manner fixed with respect to motion, and the cutouts having among one another the same size and the same spacings and a preferably identical radial position. In order to achieve an exact position of the individual image recording surfaces in the film gate of the camera with the aid of simple means, it is proposed to provide a latch stud (1a; 32), which is at rest with respect to the film feed device (7, 6 or 23, 4), has a stop edge (1b; 32a), which is on the end side in the film feed direction (counter-clockwise), and an inclined face (1c; 32b) joined thereto and dropping counter to the film feed direction, and is intended for sequentially occurring engagement in the film-side cutouts (2b), and to provide means (13; 17, 18; 21, 22b) with the aid of which the edge of one of the film-side cutouts (2b) that is in each case at the front in the film feed direction can be brought to bear against the stop edge (1b; 32a) and retained after a film feed step. <IMAGE>
Patent DE-3207433-A1 (DE)
Title: Water-tube boiler with grate firing
Inventor: WIESER RUDOLF DR
IPC: F23L9/02
Filed: 1982-03-02
Abstract: The aim of the invention is the advantageous change-over of oil-fired or gas-fired water-tube boilers to grate firings. In this connection, after the conversion of the boilers, their nominal steam generating capacity is to be achieved fully again. Furthermore, the existing contact heating surfaces of the boiler are also to be taken over extensively unchanged, but the maximum flue gas speed in them is to be reduced. Additional contact heating surfaces are to be installed in order to achieve adequate cooling of the flue gases at the lower combustion temperatures of the coal firing. These aims are achieved by the arrangement of ancillary blocks which are connected on the flue-gas side parallel to the existing contact heating surfaces of the boiler. On the side of the cooling media (feed water, steam) also, the ancillary heating surfaces are connected parallel in terms of flow to the existing contact heating surfaces of the boiler. In order to reduce the size of the grate necessary, combustion air is blown onto the grate via a system of cooled secondary-air ducts, as a result of which an intensification of the combustion process is achieved. <IMAGE>

Title: Method for suspending a ventilation duct
Inventor: KOCH EMIL DIPL ING
IPC: F16L3/00
Filed: 1982-09-09
Abstract: A method, and a device for carrying out the method, for suspending a ventilation duct consisting of pipe parts and shaped pieces (connection pieces, fittings, flanges) and having supporting elements engaging on the pipe and suspending devices for the same, are proposed, the shaped pieces at the same time serving as supporting elements, so that, upon assembly, first the shaped pieces can be mounted by means of the suspending device and then the pipe parts can be mounted on the shaped pieces. For this purpose, tabs or the like for engaging the suspending device are arranged on the shaped pieces. Furthermore, a series of practical embodiments of the device are proposed. A particular advantage of this proposal is that whole sections of shaped pieces and pipe parts can be preassembled on the ground or even at the supplier's works and then are suspended as a whole section in situ from the shaped pieces. On the one hand, a lot of working time is saved and, on the other hand, it is possible to reduce substantially the number of suspending devices required.

Patent DE-3237670-A1 (DE)
Title: Pantograph isolating switch
Inventor: ZUERCHER ERNST
IPC: H01H31/36
Filed: 1982-10-11
Abstract: The contact pressure between the contact pieces (1, 2 and 7) of the switched-on pantograph isolating switch is applied by elastic pretensioning of the bars (3, 4, 5, 6, 31, 41, 51, 61) of the pantograph. The bars are supported in this position in the drive housing (8) by a locking mechanism. The column (11) is in this case not stressed. A delayed-action coupling (14) is installed between the drive (12) and the locking mechanism. At the start of a switching-off movement, the drive shaft (13) initially rotates in a freewheeling manner and its stops (15) then strike against the coupling tube (16) connected to the column (11), releasing the locking mechanism of the pantograph in the drive housing (8). The energy stored in the pantograph by elastic pretensioning is now suddenly released and moves the two moving contact pieces (1, 2) at high speed away from the fixed contact piece (7) until the extinguishing distance is reached. Thereafter, the pantograph assumes the speed provided by the drive (12). As a result of the rapid relative movement between the contact pieces (1, 2, 7) at the start of a switching-off movement, short arc times can be achieved, as a result of which the contact pieces (1, 2, 7) are prevented from fusing together, and the production of overvoltages is prevented. <IMAGE>

Title: Swinging lift-over means with load path-switching double drive
Inventor: HETTLER PAUL
IPC: B65G47/90
Filed: 1982-12-13
Abstract: The swinging lift-over means is particularly intended for devices for loading mass-produced goods which are fed to the device by means of a conveyor belt, taken from the latter by means of special holding devices and transferred into waiting receptacles, usually large cardboard boxes. In this case, the load is to be lifted with parallel guiding, moved horizontally and set down again. Owing to the fact that the installations take up a lot of space, a displacement-controlled horizontally movable lifting crane is usually employed here which must, however, be accompanied by an elaborate parallel guide means. The device according to the invention represents a more favourable solution to the above-described object; in particular the apparatus can be made more compact and lightweight by combining the moving masses into the vicinity of a swivel point. The lift-over times become shorter and the energy requirement is reduced. The vertical and horizontal movement of the load is achieved by means of a swivel drive in conjunction with a lifting cylinder, the movements of the two elements requiring a combined control. For the parallel guiding of the load which is suspended on a pivot point and can also be rotated horizontally, there is an expanding cable guide. Fig. 1 is a diagrammatic illustration of the lift-over system, the load 11 passing along the transport path A into the positions I-IV by means of movements of the cylinder 10 and the swivel motor 2 which are simultaneous but whose directions are reversible. Fig. 10 shows the system for the parallel guiding of the load in the two... Original abstract incomplete. <IMAGE>
